Реферат:	eng: The effect of melting on the intrinsic stability of steady-state combustion of energetic materials has been analytically studied using the Zeldovich-Novozhilov approach. Stability limits are given in conventional and modified sensitivity parameters coordinates. Their dependence on the melting heat and temperature is explained in a simple way. Numerical calculations based on an original mathematical model were performed to verify the effects of melting on the stability of pressure-driven combustion regimes. Qualitatively, the effect of melting heat on the stability of transient combustion regimes with developed gas phase reactions is the same as that on the stability of steady-state regime, that is, as the melting heat increases, the stability decreases. In addition, the effect of melting temperature on the burning rate response to harmonic pressure oscillations has been numerically studied. The effect appears to be qualitatively the same under stationary and transient regimes, that is, as the melting temperature increases and approaches the temperature of the burning surface, the response function decreases noticeably in its absolute value, which corresponds to an increase of combustion stability.
